ANNEX III Specific ecodesign requirements for NRVUs, as referred to in Article 3(2) and 3(4) 1. From 1 January 2016: — All ventilation units, except dual use units, shall be equipped with a multi-speed drive or a variable speed drive. — All BVUs shall have a HRS. — The HRS shall have a thermal by-pass facility. — The minimum thermal efficiency η t_nrvu of all HRS except run-around HRS in BVUs shall be 67 % and the efficiency bonus E = ( η t_nrvu – 0,67) * 3 000 if the thermal efficiency η t_nrvu is at least 67 %, otherwise E = 0. — The minimum thermal efficiency η t_nrvu of run-around HRS in BVUs shall be 63 % and the efficiency bonus E = ( η t_nrvu – 0,63) * 3 000 if the thermal efficiency η t_nrvu is at least 63 %, otherwise E = 0. — The minimum fan efficiency for UVUs ( ην u ) is — 6,2 % * ln(P) + 35,0 % if P ≤ 30 kW and — 56,1 % if P > 30 kW. — The maximum internal specific fan power of ventilation components ( SFP int_limit ) in W/(m 3 /s) is — for a BVU with run-around HRS — 1 700 + E – 300 * q nom /2 – F if q nom < 2 m 3 /s and — 1 400 + E – F if q nom ≥ 2 m 3 /s; — for a BVU with other HRS — 1 200 + E – 300 * q nom /2 – F if q nom < 2 m 3 /s and — 900 + E – F if q nom ≥ 2 m 3 /s; — 250 for an UVU intended to be used with a filter. 2. From 1 January 2018: — All ventilation units, except dual use units, shall be equipped with a multi-speed drive or a variable speed drive. All BVUs shall have a HRS. The HRS shall have a thermal by-pass facility. — The minimum thermal efficiency η t_nrvu of all HRS except run-around HRS in BVUs shall be 73 % and the efficiency bonus E = ( η t_nrvu – 0,73) * 3 000 if the thermal efficiency η t_nrvu is at least 73 %, otherwise E = 0. — The minimum thermal efficiency η t_nrvu of run-around HRS in BVUs shall be 68 % and the efficiency bonus E = ( η t_nrvu – 0,68) * 3 000 if the thermal efficiency η t_nrvu is at least 68 %, otherwise E = 0. — The minimum fan efficiency for UVUs ( ην u ) is — 6,2 % * ln(P) + 42,0 % if P ≤ 30 kW and — 63,1 % if P > 30 kW. — The maximum internal specific fan power of ventilation components ( SFP int_limit ) in W/(m 3 /s) is — for a BVU with run-around HRS — 1 600 + E – 300 * q nom /2 – F if q nom < 2 m 3 /s and — 1 300 + E – F if q nom ≥ 2 m 3 /s; — for a BVU with other HRS — 1 100 + E – 300 * q nom /2 – F if q nom < 2 m 3 /s and — 800 + E – F if q nom ≥ 2 m 3 /s; — 230 for an UVU intended to be used with a filter. — If a filter unit is part of the configuration the product shall be equipped with a visual signalling or an alarm in the control system which shall be activated if the filter pressure drop exceeds the maximum allowable final pressure drop.
